Trailer Brakes

Yes, I'm a newbie and yes this is my first Mastercraft boat. Finally fulfilled my childhood dream.
The drum brakes never worked on my trailer and I'm going to switch up to disc however I'm hoping someone can give me specs on the trailer such as axle and bearing size so I know what kit to get. It is a 1992 Prostar 205 with original Mastercraft single axle trailer. Any help is greatly appreciated.

I am no expert but if you put this...DISC BRAKES site:www.mastercraft.com....into a google search it should get you started.

if you are switching the 5 on 4-1/2 your bearing part is

inner # L68149 bearing - race L68111
outer # L44649 bearing - race L44610
seal # 58846 double lip

the disc rotor needs to match the drum 10"

this is what will replace your current

the key to the project is this.

You are the MAN!!! Thank you so much, it seems like it would be so simple to find these specs. I e googled for hours and never got solid information. Looks like Titan or Kodiac will be ordered this afternoon.
Thanks again.

After doing some research I've found out that Titan, Kodiac and Tie Down replacement disc kits are garbage and utilize odd size bearings and parts. I've decided for the extra $100 I'd go with A complete UFP drum to disc conversion kit and replace the entire UFP A-60 slide assembly for a new complete unit. Fingers crossed this is a relatively easy project, God knows every other damn thing I've touched around the house has turned into a train wreck. If you see this reply Mikeg205 I have one other question maybe you could help with as it seems you are the MC God. Any idea's on replacing the ski locker door in floor, it has gotten spongey. Don't know if the make a replacement or if I should try and rebuild it with some marine plywood wrapped in glass.

You would have to build a new ski locker - you could probably rent the right tools to get the metal bent in the right way - or make one out of wood - which is what I would do then reinforce with aluminum angle pieces.

will they fit the current spindle on your trailer? For an extra $100 - I wouldn't look back.. especially when safety is involved.

Yes everything from UFP is factory spec and basically common sizes if parts or bearings are needed. With the other 3 products the inner bearing diameter is spec for the stock spindle but the outer bearing side for the rotors are an off/odd size only available from the distributed at a much higher price. After speaking to Cal Trailer the guy told me UFP is a superior product with almost no fail rate if maintained and that they specifically stay away from the other 3 brands. I'd spend twice as much for longevity and peace of mind on the road, a hundred bucks for a far more superior product is a no brainier. Mike thanks again for all your knowledge!! I think I'll give it a poke building a new door with reinforcement and sandwiching it in fiberglass.
